Description of activity

Students are presented with the following scenario:

‘A spotty octopus has 8 legs. Altogether there are 16 spots on his legs. Each leg has the same number of spots. How many spots are on each leg?’

They use a drawing to solve the problem and record their answer.

The suggested time for this activity is 20 minutes.

Suggested materials

Blank paper, pencils/crayons
Optional: computer drawing program

Prior learning

Students have had practice rote counting and counting groups of objects using one-to-one correspondence. They have had experience grouping and sharing collections of objects and recording informally. The teacher has modelled problems for students to solve using everyday language.
